I was excited about this product at first, but after using it I found it did not really work with any of the guys that were using it on my team. Even the best result we could get was not adequate. I like the concept but it is a poor execution. I finally quit using it during our game and was told the only one who came in clear was me through the mic on the radio. I think the trade off of having no background noise is not a good enough reason to purchase these, I would rather have a little noise and be able to understand what is being said.

Conclusion:

Don't bother, get the cheapy mic's at Radio Shack with the ear piece and PTT button. You'll have the same results.
